Thus, the definition of a class II device was changed from ‘‘performance standards’’ to ‘‘special controls.’’ In order for a device to be reclassified from class II to class I, the agency must determine that special controls are not necessary to provide reasonable assurance of its safety and effectiveness. jlentini on PROD1PC65 with NOTICES III. Background In the Federal Register of July 16, 1982 (47 FR 31130), FDA issued a final rule classifying the breathing frequency monitor into class II (§ 868.2375). The preamble to the proposal to classify the device included the recommendation of the Anesthesiology Device Panel. The Panel identified the following risks to health associated with the use of the devices: (1) Failure of the device or alarm may cause abnormal conditions to go undiscovered and result in serious patient injury or death and (2) if the device does not monitor the patient’s breathing frequency accurately he/she may receive incorrect therapy. In the Federal Register of September 4, 1979 (44 FR 51726), FDA issued a final rule classifying the electroencephalograph into class II (§ 882.1400 (21 CFR 882.1400)). The preamble to the proposal to classify the device included the recommendation of the Neurological Device Panel. The Panel’s recommendation identified the following risks to health associated with use of the device: (1) Misuse of the device as a result of using untrained persons may result in improper diagnosis and treatment; (2) misdiagnosis of the physiological symptoms could cause a misdiagnosis and lead to improper treatment of the patient’s neurological condition; and (3) electrical shock could be associated with current leakage of the device, making it hazardous because the device makes a low resistance contact with the patient. On August 18, 2004, IM Systems submitted three petitions requesting FDA to reclassify the SleepCheck device, the ActiTrac, and PAM–RL devices from class II to class I (Ref. 1). Under 21 CFR 860.120(b) the reclassification of any device within a generic type of device causes the reclassification of all substantially equivalent devices within that generic type of device. IV. Device Description The SleepCheck device is classified within the generic type of device called the breathing frequency monitor (§ 868.2375). FDA identifies the breathing frequency monitor as a device intended to measure or monitor a patient’s respiratory rate. The device VerDate Aug<31>2005 17:44 Jul 13, 2006 Jkt 208001 may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. The ActiTrac and PAM–RL devices are classified within the generic type of device called the electroencephalograph (§ 882.1400). FDA identifies the electroencephalograph as a device used to measure and record the electrical activity of the patient’s brain obtained by placing two or more electrodes on the head. V. FDA’s Decision After reviewing both the reclassification petitions and the petitioner’s responses to our subsequent requests for information, FDA has found that the petitions do not contain any valid scientific evidence to support a conclusion that general controls would provide reasonable assurance of the devices’ safety and effectiveness for their intended uses or that special controls are not necessary to provide reasonable assurance of the safety and effectiveness of the devices. Therefore, FDA is denying the petitions for reclassification of these device types. VI.

Method for Expanding Allodepleted Antigen Specific T Cells Description of Technology: Available for licensing and commercial development are methods of producing a population of purified nonalloreactive antigen-specific T cells that recognize an antigen of interest. Thus, the population of donor T cells can be used to produce immune response against the antigen of interest (e.g., cytomegalovirus) in a recipient without producing an immune response to the recipient. Currently available methods for isolating and expanding antigenspecific T cells can be inefficient and produce populations of cells that include donor-reactive T cells. The present method enables rapid production of populations of T cells that recognize an antigen of interest but are depleted for alloreactive T cells: A population of donor T cells is contacted with a population of irradiated recipient antigen presenting cells (T–APCs) to produce a population of alloreactive T cells. The alleractive T cells are removed by purification with an antibody that specifically binds a cell surface marker (e.g., CD25, CD69, CD38 or CD71). The population of allodepleted donor cells is then contacted with donor T antigen presenting cells (T–APCs) expressing an antigen of interest and produces a population of donor allo-depleted activated CD4 and CD8 T cells.

A Newly Discovered Bacterium in the Family Acetobacteraceae Description of Technology: Available for licensing and commercial development is a newly discovered bacterium in the Acetobacteraceae family. This bacterium was isolated, characterized and grown from lymph nodes of a patient with chronic granulomatous disease (CGD), a rare genetic disorder that impairs the immune system. This Gram-negative bacterium is an aerobic, faculatitive methylotroph that produces yellow pigmented colonies.

Coacervate Microparticles Useful for the Sustained Release Administration of Therapeutics Agents Description of Technology: The described technology is a biodegradable microbead or microparticle, useful for the sustained localized delivery of biologically active proteins or other molecules of pharmaceutical interest. The microbeads are produced from several USP grade materials, a cationic polymer, an anionic polymer and a binding component (e.g., gelatin, chondroitin sulfate and avidin), in predetermined ratios. Biologically active proteins are incorporated into preformed microbeads via an introduced binding moiety under nondenaturing conditions. Proteins or other biologically active molecules are easily denatured, and once introduced into the body, rapidly cleared. These problems are circumvented by first incorporating the protein into the microbead. Microbeads with protein payloads are then introduced into the tissue of interest, where the microbeads remain while degrading into biologically innocuous materials while delivering the protein/ drug payload for adjustable periods of E:\FR\FM\14JYN1.SGM 14JYN1 Federal Register / Vol. 71, No. 135 / Friday, July 14, 2006 / Notices jlentini on PROD1PC65 with NOTICES time ranging from hours to weeks. This technology is an improvement of the microbead technology described in U.S. Patent No. 5,759,582. Applications: This technology has two commercial applications. The first is a pharmaceutical drug delivery application. The bead allows the incorporated protein or drug to be delivered locally at high concentration, ensuring that therapeutic levels are reached at the target site while reducing side effects by keeping systemic concentration low. This microbead accomplishes this while protecting the biologically active protein from harsh conditions traditionally encountered during microbead formation/drug formulation. The microbeads are inert, biodegradable, and allow a sustained release or multiple-release profile of treatment with various active agents without major side effects. In addition, the bead maintains functionality under physiological conditions. Second, the microbead and microparticles can be used in various research assays, such as isolation and separation assays, to bind target proteins from biological samples. A disadvantage of the conventional methods is that the proteins become denatured. The denaturation results in incorrect binding studies or inappropriate binding complexes being formed. The instant technology corrects this disadvantage by using a bead created in a more neutral pH environment. it is the same environment that is used for the finding of the protein of interest as well.

Methods and Compositions Related to GHS–R Antagonist Description of Technology: This invention describes that additional functional role for D–Lys3 GHRP–6 (a known GHS–R antagonist, peptide) as a blocker of two well-known chemokine receptors, namely CCR5 and CXCR4. These receptors are major HIV coreceptors and are critical for HIV binding, fusion and entry into human T cells, monocytes, dendritic cells, and various other cells within the body. VerDate Aug<31>2005 17:44 Jul 13, 2006 Jkt 208001 Moreover, these receptors and their ligands play a major role in inflammation and a variety of acute and chronic disease states. Overall, these two mammalian chemokine receptors are currently major drug targets for treatment of AIDS, cancer and many immunoregulatory disorders. Many identified antogonists block one or the other receptor. Since D–Lys3 GHRP–6 actually binds and blocks both these chemokines receptors at the same time hindering their activity and HIV infectivity, D–Lys3 GHRP–6 may be a good therapeutic candidate for treatment of AIDS and inflammatory diseases.

Method for Expanding Allodepleted Antigen Specific T Cells

    Description of Technology: Available for licensing and commercial 
development are methods of producing a population of purified non-

interest. Thus, the population of donor T cells can be used to produce 
immune response against the antigen of interest (e.g., cytomegalovirus) 
in a recipient without producing an immune response to the recipient. 
Currently available methods for isolating and expanding antigen-
specific T cells can be inefficient and produce populations of cells

denatured, and once introduced into the body, rapidly cleared. These 
problems are circumvented by first incorporating the protein into the 
microbead. Microbeads with protein payloads are then introduced into 
the tissue of interest, where the microbeads remain while degrading 
into biologically innocuous materials while delivering the protein/drug 
payload for adjustable periods of

time ranging from hours to weeks. This technology is an improvement of 
the microbead technology described in U.S. Patent No. 5,759,582.
    Applications: This technology has two commercial applications. The 
first is a pharmaceutical drug delivery application. The bead allows 
the incorporated protein or drug to be delivered locally at high 
concentration, ensuring that therapeutic levels are reached at the 
target site while reducing side effects by keeping systemic 
concentration low. This microbead accomplishes this while protecting 
the biologically active protein from harsh conditions traditionally 
encountered during microbead formation/drug formulation.
    The microbeads are inert, biodegradable, and allow a sustained 
release or multiple-release profile of treatment with various active 
agents without major side effects. In addition, the bead maintains 
functionality under physiological conditions.
    Second, the microbead and microparticles can be used in various 
research assays, such as isolation and separation assays, to bind 
target proteins from biological samples. A disadvantage of the 
conventional methods is that the proteins become denatured. The 
denaturation results in incorrect binding studies or inappropriate 
binding complexes being formed. The instant technology corrects this 
disadvantage by using a bead created in a more neutral pH environment. 
it is the same environment that is used for the finding of the protein 
of interest as well.

Methods and Compositions Related to GHS-R Antagonist

    Description of Technology: This invention describes that additional 
functional role for D-Lys3 GHRP-6 (a known GHS-R antagonist, peptide) 
as a blocker of two well-known chemokine receptors, namely CCR5 and 
CXCR4. These receptors are major HIV co-receptors and are critical for 
HIV binding, fusion and entry into human T cells, monocytes, dendritic 
cells, and various other cells within the body. Moreover, these 
receptors and their ligands play a major role in inflammation and a 
variety of acute and chronic disease states. Overall, these two 
mammalian chemokine receptors are currently major drug targets for 
treatment of AIDS, cancer and many immunoregulatory disorders. Many 
identified antogonists block one or the other receptor. Since D-Lys3 
GHRP-6 actually binds and blocks both these chemokines receptors at the 
same time hindering their activity and HIV infectivity, D-Lys3 GHRP-6 
may be a good therapeutic candidate for treatment of AIDS and 
inflammatory diseases.
